TANK.

Application led February 29, 1928, Serial No. 258,068, and in Cuba December 19, 1927.

This invention relates to tanks and espes cially to low closet tanks, aud has ttor its main object to provide an arraixgement et` devices such as to cause the filling' of the tank at will, and the subsequent autlunatic total discharge ot same within a short space et time, the tank remaining completely dry, until a new discharge delivered.

An object therefore oli lny invention is to provide a tank -lrolu which leakage of water into the bowl can not occur as occurs in tanks known up to the present time, and in which a. complete and automatic discharge takes place.

A Further object of the invention is to provide a device vfor this purpose, which includes a spring' cock, and which device is ot a simple and durable construction, and easily operated.

ln the drawings:

Figure 1 is a top plan view of the tank oit' the present invention.

Figure 2 is a vertical longitudinal section on line @M2 of Fig. 1,

Figure 3 is a view similar to Fig. 2 illus trating' various operative positions of the parts.

Figure l is a iragru'ientary sectional. view in detail, taken on the line 4-4 of Figure 2, and

Figures Band 6 are detail views et parts ol the discharging; mechanism of the tank.

In the drawinathe numeral 1 designates a closet. tank oit a low ty pe. 2 being' the inlet pipe oil? saine, in which pipe is intercalated a spring: l

cock 3. Secured to the stein of this cock is an angular lever l. pivoted` at 5 axially o1 said spring;- cock and provided with a counter weg'l'lt 4l. The short arm of this lever 'is connected. with a red 6 bent in a bayonet shape, 'which is operated from the outside by the handle 7 connected to the saine, and giviupr to same an eccentric gyratory moveuleut; the long' arm ot the lever is adjustable by means of a screw 4, and bears on its end. a pawl 8, pivoted in such a way as to swing upwardly, but not downwardly, as seen in Figures and 6, and which cooperates with the disk 9, secured to the upper end oilt the tred 1() of a ball valve 11, the latter restingv on a seat 12 in the discharge pipe 13 oit the tank. The, rod is held and 1e'uided thru brackets 14 secured to the outlet pipe 1e ot the tank.

The 'fioat 16 ot the tank is provided with the rod 17 which ends in a trigger 18 and. is pi'voted at 19 to the inlet pipe 2. and connected in a Way which will be eaplained further along, to an eccentric rod 6 to which the handle 'l' is connected.

'lhceperation of the mechanism described is as explained in the following:

fnupposinp,- the parts to be in an inactive or idle position shown in Figure 2, that is to say` the tank empty, and the pawl 8, raised over and in spaced relation to the disk 9 of the rod. of the valve 12. v

it the handle 7, secured to the rod 6 is made to turn in one direction, this rod will ride against the short arm of the lever 1 and will move the same upwardly, turning' the long arm et said lever which bearsthe pawl S downwardly, said pawl when coming in en- `iragement with the disk 9 turning upwardly and riding' past the disk 9, as seen in Figure 5, pern'iitting' said long' arm to descend to a lower level than said disk, as shown in Figure 3; at the same time the spring' cock 3 to which the lever 4 is fastened'will be opened, K

As the tank is being' lilled the float 16, held by the rod 17, on the end of which is secured. thetrigg'er 18, which presses the rod 6, will rise, until trigger releases the short armv of the lever 4l, and same hy the reaction of the spring' of the cock 3 and the counter weight 11, will return to its initial position closing' said cock. and inA this movement the pawl 8 which has nodownward movement, will engage the disk 9, as shown in full line in Fig;L ure G, raising' the rod ot the valve 11, as shown in dotted lines in the same Figure, and producing' the immediate discharge of Water 'from the. tank, thru the pipe 13 controlled by said valve. As it will be seen the tank 1 will necessarily remain substantially empty, until it be desired to produce a new discharge, which will be done in the manner already eX- plained.

It' thought convenient, outlet passages 20 may be provided, to the discharge pipe 13, for the outlet to the bowl of the small amount oil water which remains in the tank 1, after the discharge.

I claim:

1. A flushing' tank having connected to it a water supply pipe and a water outlet pipe, inlet and discharge valves controlling the flow of water through said pipe, respectively, said inlet valve being' of the self-closingr type, an angle lever connected to the stein et the inlet 'mi e el; aff-i'. rufen-usd. tor rotative. movement Cil and having an arm extending,` therefrom tor engagement with one arm oit said angle lever whereby, upon manual rotation ot said shaft, in one direction, the arm will coaet with one arm ot the angle lever to lock the same and to ell'ect opening of said valve, the arm ot the shalt @instituting means 'eor maintaining` the angle lever in position with. the inlet valve open, an abutment element upon the stem ot the outlet valve, and a pawl pivotally mounted upon the other arm ot the angle lever and tree to move upon its pivot in one direction and restrained against movement in the other direction and constituting` means tor coaction with the abutment upon the stem ot the discharge valve, in the automatic movement ot the angle lever with the stem ot the inlet valve when the angle lever is released by the movement oit the arm upon said shatt, out ot engagement therevvith, whereby to provide tor automatic opening` oit the discharge valve upon closing oli the inlet valve, a pivoted rod, a lioat mounted upon the rod on one side ot its pivot and means at the other side ot the pivot tor the arm tor engagement with the arm upon the said manually operable shaitt to ell'fect disengagement ot the shatt arm from the arm et the angle lever upon rise et the float in theetanl, the pivotal mounting of the pawl providing for its passage past the abutment upon the stem of the discharge valve in the movement of the angle lever with the stem ot the inlet valve when the valve is moved to open position.

2. A flushing tank having connected to it a water supply pipe and a water outlet pipe, self-closing inlet valve controlling the tlow oit Water through the supply pipe, a discharge valve tor controlling the tlow ot water l'rom the tank through the outlet pipe, a manually rotatable sha'lt, an arm extending therefrom, a lever mov ble with said inlet valve and havinn,l an arm engageable by the arm upon the rotatable sha'lt when said shalt is manually rotated in one direction and constituting means whereby the valve may be moved to open position, the engagement et the arm ot Lhe lever with the arm upon the sha'lt serving to prevent sel'li-closinp, oit the inlet valve, and abutment upon the stem ot the discharge valve, means upon the said lever for engagement with the abutment in the movement el' the lever, when released by disengagement ot' the arm upon the shat't trom the arm ot the lever, to etl'ect openi ng ol the dir-acharge val ve, and tor coactien with the abutment upon the stem oit the discharge valve 'lor moving' the valve to open position when the inlet valve moved to closed position, a tloat, and means movable by the rise ot the {loat in the tank to coact with the arm upon the rotatable shalt to disengage the same trom the arm et the said lever.

3. ln tanks connected to a water supply and water outlet, inlet and discharge valves controlling' respectively said supply and outlet, a lever connected to said inlet valve having means normally holding it in a position to close said inlet valve, means ca ried said lever lior opening; said discharge valve when said inlet valve is closed, manually operable means 'tor movin gr said lever to open the inlet valve, the lever havingv means tor coaction with a part ot the manually operable means to latch the valve in said position. and simultaneously move said discharge valve to open position, a float Within the tank, and means actuated through rise ot the float in the tank 'for releasingl said lever to provide tor simultaneous closing ot the inlet valve and movin g et the discharge valve to open position, the said means comprising an abutment elenient associated with the discharge valve and a pawl associated with said lever and engageable with the abutment lo ellect the movement oit the said discharge valve to open position upon movement ol the le ver at the time ot' its release.

ln testimony wl'ioreot l have signed my name to this specification.
